Sources tell Us Weekly the couple has ended its engagement.
"Emma and Evan were heading for a split and now are just friends," an insider tells the publication. "Evan has moved out. It wasn't a bad break-up."
"Garrett and Emma have been friends, but this is new, casual, and just a couple of weeks old," a source says.
Emma and Evan had been together, on and off, since 2012.
Last year (18) he revealed the actress sneakily switched place cards at a dinner party years ago, so she would be seated next to him.
"We met at a Mexican restaurant party-type thing...," he recalled on morning show "Live with Kelly and Ryan". "It was a sit down thing and there were name cards, and she switched a name card so that we could sit next to each other. She made the switcheroo (sic)! God love her!"
Evan had no idea who was originally supposed to be seated next to him at the group dinner, but he remembers enjoying the first conversation the couple shared - even though he was hesitant to suggest their chemistry was instant.
"She was hilarious," he said. "We laughed a lot and we had a great time."
The couple began dating after the dinner party and became engaged in December 2013.
Just months before Evan proposed, Emma was arrested amid allegations of domestic violence following a dispute with the actor in Canada. At the time, her representative dismissed the bust-up as an "unfortunate incident and misunderstanding" and claimed the stars were "working together to move past it."
They ended up parting ways in the summer of 2015, before reconciling and breaking up again in June, 2016. They reunited once more and became engaged for a second time that winter.
